Screwed on 'the upper end of the cap is e@ inhular union 30 provided et' its upper end with inwnrfily extending flange Seated on the upper end. of he union" is :i wheel or handle 34 provided en iis under sirie with en enreriorli ilreeded heb 3G arranged in end projecting "ihrengh the opening' 38 in the union iange 32 and having herein e verical square opening 3'?. Screwed 0n to he lower enel of the hub 36 is :in inl'eriorly hreefie ring i0 engaging the under side or the flange and ecliiped to prevent he displacement of he handle. Said ring fi() should 'be provided on iis under sideiviih two suitable openings or notchee 42 shown in Fig. 2 to receive ilie prongs of e forked Wrench or key by ineens of which the ring;

noie beween `rire ring and 'nnb and inserting therein e pin er screw es 44 shown in Fig. 2.

Rotninhly er zingei in the threaded openingr 18; in the bonnet heed, is a 'thi-ended valve siem 4G having ire, ripper. end squared and carrying on its opposite end e vulve heini e8 having n ieee i9 itting seid seat 1 0. .firrangeii in ehe henne? is :i tubular valve'seln emensinn 5S :wing in: lower eni arranged end having en inerior 52 eliilniilvfiling he upper 'f'v :iinlvn'oviileal willi un exhandler nnien terior annular {iange engaging the under side of the gasket 28 having a iortion lit-ting the circular opening 24rinthe cap nd provided on its upper end with a l e shank 56 itting the opening 3 handle.

Surrounding the stein entensi Seated on the bonnet head a made oi' fiber, vuleanised rubber o and'having its upper tace curved and sloping upwardly from the outer to the inner edge as shown. Seated on the latter is a metal Washer G having its lover inner edge rounded as shown to it the upper face of the gasket. Surrounding thei'stein exten-- sion and engaging the lower side oi' 'the annular flange d is a. niet-al washer 62.

,Arranged in the bonnet and surrounding the stem extension is a coil spring inning its opposite ends engaging and pressing 'against the said metal washers whereby the the the gasket 58 is pressed firmly against bonnet head and the adjacent endy oi stein extension to prevent tluid entering' bon-net, and theliange .5e pressed again gasket 28 and the latter held iirn'ily ag" the stein extension and the bottom an wall of the counterbore 2G in anch inenner as to prevent iluid which may enter the bonnet from passing between the gasket ar l the stem extension or cap.

The washer 60 may carry one or more pins 66 having their lower seated in open-- lings 68 formed in the upper r ytee er bonn net head.

The Valve just described may be closed and opened by rotating to the right left the handle which in turn rotates the stein ei;- tension which in turn rotates the stein which when thus rotated moves endwise and slides in the opening 52 and and lowers the valve head.

In theinodilied form, shown in 3, the construction is the saine as in 1 excei'it, that the stein extensionl has in its upper end 'a square opening 53 in place oi2v the shank 5G on the stern extension 50. Second: that, the handle 85 has its central opening 89 extending through it. Third:` than, the handle and stein extension are connectedby a key 41 havine an annular flange ,seated on the top of the cap and having its lower end titting the opening 5.3 in the stein extension and having its upper end fitting the opening 39 in the handle and carrying on its ripper end a nut 45 :tor preventing the displaceinent of the handle, Fourth: that, the ring 40 is dispensed with, And fifth: that,

" 'In the valve of yinodiiied shown' in Fig. fl, 5 represents afraginent of the union 31 is shorter than the union El@ he cause'the ring 1G is not employed.

construction the valve body; 15 the bonnet provided at its lower end with a head 1'? having a threaded central opening 19 to rece-ive the threaded valve stein 46; 28 a cap screwed on the upper end of the bonnet and provided with a conical central opening 25 having its upper end smallest; a. valve stein extension 7 having a conicai shaped portion or flange 9 7'()y fitting said conical opening 25 in the cap and having in its lower end a square open 'ing i1 to slidably receive the square end of the stein #i6 and provided on its outer end with a handle 21; G2 a metal washer sur- '75.

rounding the ste-m extension and engaging the lower end oi the conical iiange. 9; and 64- a coil spring arranged in the bonnet and having.;l its opposite ends pressing against the bonnet head and washer respectively Whereby the steam or other fluid is prevented from passing between the cap and the conleal Hange.

Either of stein extension flanges and the washer S2 may be made integral or the 85 washer dispensed with and the lower part of the tiangevincreased in diameter t0 enthe spring.

i. preferably use in either form of valve niy cast iron spring'described and claimed in 90 Patent No. 843,827 issued Feb. 12, 1907, as this spring is not detempered by heat.

is certain changes other than those nien? tioned might be made in the construction snown and described without departing from the spirit ci' myl invention I do not wish to be confined to the exact detail constructions shown or described.

"dihat claim, is:

1. The combination with a casing provided with an inlet and an outlet port, a ralve arranged between said ports, a bonnet having threaded connection with said casing, a. head for said bonnet having a central threaded opening and provided With an annui lai: groove surrounding said opening, a valve stem engaging said opening, a squared p0r tion on said stem extending above the bonnet h'cad, and a cap for the bonnet, of a tubular stein extension rotatable in said annular groove' and provided with a suitable opening slidably engaging the squared por,-

tion of the valve stem, an angular shank on the said'I stein extension, and an operating device secured to the cap andadapted to 116 engage said shank.

v Q.. The combination with a casing pro vided with an inlet and an outlet port', a valve arranged between said ports, 'a bonnet having threaded connection with the casing, 120

a head forw ,said bonnet having a central threaded. opening and provided With an annular groove surrounding said opening,l a

valve stein engaging said opening, a squared portion on said stein extending above the portion of the 'valve 130 stein, a gasket having a sloping face sur-v rounding said extension adjacent said bonnet head, a Washer having a rounded margin engaging the slopiiigface of Said gasket, a coiled spring bearing against said washer, an angular shank on the said stein extension, and an operating device secured to the cap and adapted to engage said shank.'

3, The combination with a easing provided Witli au inlet and an outlet port, a valve arranged between said ports, a bonnet having threaded connection with the easing, a head 'for said bonnet having a central threaded opening and provided with an aniiular groove surrounding said opening, a

valve stein engaging said opening and havinga squared portion extending above the bonnet head, anlja cap for the bonnet, of a tubular stein extension Seated in saidannii-v lai' groove and rotatable therein, said eX- tension having a Suitable opening s lidably and provided with a sloping face, a lowerwasher having a rounded inner margin engaginv the sloping face of said gasket, a second gasket .interposed between said flange on the stein extension and the cap, a coiled 'spring arranged Within the bonnet and having its ends bearing against Said Washers, au angular shank on the stein extension, and
